/>施工現場(chǎng)踏勘材料：<br />我企業(yè)現場(chǎng)對施工當場(chǎng)開(kāi)展了勘驗，施工場(chǎng)所坐落于隆德縣山區地帶，出土文物點(diǎn)、下葬點(diǎn)現無(wú)大中型機器設備入場(chǎng)路面對目前的地質(zhì)學(xué)、自然地理開(kāi)展估測，地質(zhì)學(xué)遍布為粉質(zhì)粘土、泥巖、板巖、石灰巖（帶有砂礫）。<br />定向鉆施工實(shí)例工程項目關(guān)鍵內容概述：<br />隆德縣城鎮供電工程項目（一期）隆德縣城-山泉水段連接工程項目的建設方為隆德縣水利工程水保建設工程管理處，建設項目地址為隆德縣城關(guān)鎮、好水鄉古鎮。管道25 410處（打食溝水利樞紐上下游上杜家村）采水，運用原管道水口自壓通水，沿打食溝溝道左岸混泥土馬路邊鋪設管道，在打食溝水利樞紐中下游0.3公里處橫貫打食溝至十八里鋪村東，后越過(guò)青蘭高速路、312 省道、渝河河堤和工業(yè)區在樁號10 953處穿越重生逯家山，以后沿石溝右岸鋪設，.后連接好水鄉古鎮人飲工程項目已建貯水池。沿岸在三星水利樞紐上下游斷面處設定分水口，鋪設三星水利樞紐支系連接管道。逯家山穿越重生工程項目總長(cháng)1580.00m，管道規格型號D426毫米*10毫米，穿越重生管道.大埋深為153.00m。出、入鉆點(diǎn)坡比為1:2000。<br />陜西省定向鉆施工實(shí)例一、當場(chǎng)施工五大難度系數<br />1 、地質(zhì)構造：泥巖沙巖<br />2 、施工自來(lái)水：在三公里之外建造污水處理廠(chǎng)，<br />3 、新路：新路艱險，坡大溝深，<br />4 、氣候條件:持續連陰雨，導致地面泥濘不堪<br />5 、導向規定高精度1/200<br />定向鉆施工實(shí)例二、施工關(guān)鍵操縱<br />1、有效的配備機器機器設備，入場(chǎng)前對鉆機開(kāi)展維護保養，拆換易損件構件，對鉆具開(kāi)展檢驗，清理鉆具內部，對泥漿泵開(kāi)展維護保養，水壓試驗后入場(chǎng)，配備對于施工地質(zhì)構造，應用637牙輪鉆頭，配備泥漿收購系統軟件，降低需水量，配備大中型泥漿混配系統軟件，提升泥漿混配時(shí)間，提升彭化率，施工剛開(kāi)始后，定人定崗定編實(shí)施二十四小時(shí)連續施工。</p> <p><img class="wscnph" style="display: block; margin-left: auto; margin-right: auto;" src="http://aiimg.dlwjdh.com/files/images/news/1261ba6e-a40b-4772-bb0c-b46c75d0c082.jpg" /><br />2 、導向施工，在入鉆點(diǎn)、出鉆點(diǎn)開(kāi)拓100到200平方米的布電磁場(chǎng)地，進(jìn)出鉆二點(diǎn)的管位上邊盡量的多布電磁場(chǎng)，布大電磁場(chǎng)，提升校正的機遇，提升施工精密度。<br />3 、依據砂土、泥巖、板巖地質(zhì)構造的轉變，隨時(shí)隨地調節泥漿秘方，調節防腐劑秘方，必需時(shí)開(kāi)展水體改進(jìn)，充足的充分發(fā)揮泥漿的三大作用，錨桿支護、帶上、潤化等功效。<br />水平定向鉆機鋪管拉術(shù)做為非開(kāi)挖頂管技術(shù)性的一個(gè)關(guān)鍵支系，是將勘探技術(shù)性與控向技術(shù)性恰當融合的當代非開(kāi)挖頂管施工新技術(shù)應用，近些年運用于給水排水管道施工。伴隨著(zhù)導向精度等級提升、施工機器設備工作能力提高管件業(yè)的發(fā)展趨勢，走管工作能力由前期的口徑、短離、單一無(wú)縫鋼管，發(fā)展趨勢到大口徑、遠距離、多種多樣管件的鋪設，變成非開(kāi)挖頂管行業(yè)的發(fā)展趨勢關(guān)鍵，技術(shù)性上已逐步完善。<br />1、技術(shù)性特性<br />(1)運用覆蓋面廣，可用特性強。適合在粘土、砂土、碎石土等土質(zhì)條件下選用；可鋪設塑料軟管(PVC、PE等)無(wú)縫鋼管或鑄鐵排水管，管經(jīng)在DN40到DN2000中間，大中型鉆機走管長(cháng)短可做到1000m之上<br />(2) 鉆機布局靈便。打孔全過(guò)程可在事先挖好的發(fā)送坑和接受坑中間開(kāi)展，也可在安裝鉆機的場(chǎng)所，以小視角立即從土層鉆入。<br />(3)施工機器設備的穿越重生高精度，可考慮管道標高的操縱規定<br />(4)施工全過(guò)程不造成噪聲、煙塵，不毀壞地形地貌和自然環(huán)境，考慮環(huán)境保護的各類(lèi)規定。<br />(5)機器進(jìn)登場(chǎng)靈便方便快捷，針對場(chǎng)所標準規定不高，施工速度更快。<br />(6)適合于高速公路等不允許基坑開(kāi)挖或管道繁雜地域的管道施工，特別是在在穿越重生河流的新項目上更凸顯其與眾不同的優(yōu)點(diǎn)。<br />2、施工加工工藝<br />(1)早期提前準備<br />掌握管道穿越重生范疇內的地質(zhì)學(xué)標準、目前地下管道的邁向及埋深等狀況，融合設計方案規定整體規劃鉆入運動(dòng)軌跡，選中施工計劃方案(主要是選中鉆機、明確進(jìn)出土壤層的視角、鉆孔等比級數和穿越重生管件等)。<br />(2)導向鉆入<br />定項麻花鉆在鉆機的扭力功效下，由鉆機驅動(dòng)器轉動(dòng)(或應用泥漿電機推動(dòng)麻花鉆轉動(dòng))鉆削地質(zhì)構造，按設計方案打孔運動(dòng)軌跡前行，進(jìn)行全部導向孔的打孔工作鉆入全過(guò)程中，麻花鉆內數據信號棒傳出的數據信號被接納解決后，顯示信息出麻花鉆的深層、部位、視角等信息內容，由此立即調節麻花鉆方位，確保所進(jìn)行的導向孔曲線(xiàn)圖合乎設計方案規定。<br />(3)等級分類(lèi)鉆孔<br />進(jìn)行導向孔施工后，采用等級分類(lèi)鉆孔的方法將打孔擴至適合的直徑。另外將鉆液泵注打孔中，確?？籽墼敿毢筒惶?，并將鉆削下的土屑帶返回路面，為回拉管道造就適合的自然環(huán)境。<br />(4)回拉管道<br />鉆孔進(jìn)行馬上將待鋪設的管道與回拉鏈頭、鉆孔頭及鉆具聯(lián)接，由鉆機牽引帶將管道拉進(jìn)已擴打孔中，進(jìn)行管道鋪設。<br />定項鉆機技術(shù)性是以石油鉆井行業(yè)發(fā)展趨勢起來(lái)的優(yōu)秀技術(shù)性，是運用巖層鉆倔、定項鉆機測控技術(shù)等方式方法，在土層不割槽和地層結構毀壞很小的狀況下，對例如供電、液化氣、燃氣、廢水，由電信網(wǎng)電纜線(xiàn)等公共管道開(kāi)展鋪設的施工加工工藝。定項鉆機應用領(lǐng)域很廣，能夠選用孔底電機或剛度鉆具推動(dòng)麻花鉆旋轉進(jìn)成孔，在硬巖或河卵石層中也能夠開(kāi)展施工。</p>
